Subject: [PATCH v2 8/8] ARM: tegra: nexus7: Use panel-lvds as the only panel compatible
Date: Wed, 4 Nov 2020 17:12:51 +0300 [thread overview]
Message-ID: <20201104141251.25834-9-digetx@gmail.com> (raw)
In-Reply-To: <20201104141251.25834-1-digetx@gmail.com>
Depending on a driver probe order, panel-simple driver may probe first,
which results in this error:
panel-simple display-panel: Reject override mode: panel has a fixed mode
We don't want to use panel-simple anyways because customized timings are
preferred for Nexus 7, hence remove the panel-simple compatibles from the
panel node.
